1.6 litre 4-cylinder engines confirmed for 2013

The FIA has confirmed the new specification of Formula 1 engines to be used from the 2013 season onwards.

The current 2.4 litre V8s will be replaced with 1.6 litre 4-cylinder power plants. They will be assisted by high-powered injection, up to 500 bar. The engine rev limit has been reduced to 12,000 rpm.

The number of engines each driver can use will be brought down to 5. From 2014 onwards, this will be reduced to 4 per year.

The FIA claim that these new engines will deliver up to 35% reduction in fuel consumption, while providing the same amount of power (currently around 800 hp).Energy recovery systems and energy management will also be introduced, hinting that the FIA is looking at exhaust gases recovery systems to team up with the KERS unit used at the moment.
